Introduction
Sapphires have fascinated jewellery lovers for centuries, admired not only for their beauty but also for their durability and symbolism. As the birthstone for September, and a gemstone often chosen for engagement rings, sapphires are both meaningful and practical.
If you are considering purchasing a sapphire, this guide will help you understand what makes this gemstone unique and how to make an informed choice.
1. What Makes a Sapphire Unique?
- Colour: While sapphires are most famous for their deep blue hue, they exist in almost every colour except red (red corundum is classed as ruby). These alternative hues are called fancy sapphires.
- Durability: With a hardness of 9 on the Mohs scale, sapphires are exceptionally durable, second only to diamonds. This makes them suitable for everyday jewellery.
- Symbolism: Historically associated with wisdom, sincerity, and loyalty, sapphires are often chosen for significant milestones such as engagements or anniversaries.
2. Evaluating Sapphires: The 4Cs
Just like diamonds, sapphires are assessed using the “4Cs”:
- Colour: The single most important factor. The finest sapphires have a vivid, saturated colour that is evenly distributed across the stone.
- Clarity: Most natural sapphires contain inclusions. A stone with fewer, less visible inclusions is generally more valuable.
- Cut: Unlike diamonds, sapphires are often cut to maximise colour rather than sparkle. Oval and cushion cuts are popular, but the precision of the cut can greatly affect the stone’s appearance.
- Carat: Larger sapphires are rare and command higher prices. However, a smaller stone with excellent colour may be more desirable than a larger, less vivid sapphire.
3. Natural vs. Treated Sapphires
- Heat Treatment: The majority of sapphires are heat-treated to improve colour and clarity. This is a standard, permanent treatment accepted in the jewellery industry.
- Untreated Sapphires: Completely untreated stones are rare and highly valuable. If you are considering an untreated sapphire, ensure it comes with reliable certification from a recognised gemmological laboratory.
4. Sapphires in Jewellery
- Engagement Rings: Sapphires are a popular alternative to diamonds, offering durability and a striking, regal appearance. The most famous example is Princess Diana’s sapphire engagement ring, now worn by Catherine, Princess of Wales.
- Everyday Jewellery: Thanks to their hardness, sapphires are ideal for rings, earrings, and pendants designed for frequent wear.
- Birthstone Jewellery: As September’s birthstone, sapphires carry a personal meaning, making them an excellent choice for birthday or anniversary gifts.
5. Caring for Your Sapphire
- Clean using warm water, mild soap, and a soft brush.
- Avoid harsh chemicals and ultrasonic cleaners if your stone has inclusions or fractures.
- Store separately from softer gemstones to prevent scratches.
